Project description

The study will provide the Indiana Department of Transportation (INDOT) with information on how the alteration in pore solution composition due to the use of limestone cement can impact durability of concrete with respect to chemical stability of hydration products, corrosion resistance of reinforcement, sulfate resistance and performance in aggressive environment. The possible, practical deliverables of this study will include: (i) Possible changes to the current standard testing procedures, (ii) development of predictive model, based on the inter‐relationship between the chemistry of the pore solution of the Type IL cementitious system, and durability performance of the Type IL concrete.
